CLOCK.

Application filed October 14, 1911.

To all whom it may concern Be it known that It, SoLoN B. BRICKER, acitizen of the United States, residing at St. Paris, in the county ofChampaign and State of Ohio, have invented certain new and usefulImprovements in Clocks, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to clocks and has for its object the productionof a striking device for the quarter of an hour, which may beconnectedto the main striking gear of the clock, thereby doing away withthe necessity of providing a separate gear for the quarter strike.

Another object of this invention is the production of a simple andetlicient shifting means for causing the different striking arms tooperate.

With these and other objects in view this invention relates to certainnovel constructions, combinations, and arrangements of parts as will behereinafter fully described and claimed.

In the drawings: Figure 1 is a vertical fragmentary section of thestriking mechanism. Fig. 2 is a vertical section through the clock frameshowing the shifting means for the striking mechanism. Fig. 3 is avertical section through the clock casing showing the operatingmechanism for the striking device. Fig. 4: is a transverse sectionthrough the frame showing the striking mechanism operating device inbottom plan. Fig. 5 is a transverse section taken through the casingshowing the shifting mechanism in top plan. Fig. 6 is a transversesection taken through the casing showing the arrangement of the controlarms for the striking mechanism in top plan. Fig. 7 is a fragmentaryvertical section taken through the back plate of the casing showing anend View of the releasing lever and wheel. Fig. 8 is a side view of thelocking disk for the striking device. Fig. 9 is a perspective of thereleasing lever of the striking device. Fig. 10 is a vertical sectionthrough the clock frame showing the releasing lever and wheel in sideelevation. Fig. 11 is a fragmentary view of the casing showing thesupport for the clapper arms. Fig. 12 is a detail perspective of thecontrol arms and support therefor. Fig. 13 is a perspective view of theshaft carrying the counting control arm.

Specification of Letters Patent.

Patented June 1, 1912.. Serial No. 654,686.

Referring to the drawings by numerals 1 designates the back plate of theframe which supports the front plate 2 in the unsual manner by spacingbars. The main shaft 3 passes through the plates 1 and 2 and carriesnear its end a cam-star wheel 1 upon which rests the curved end 5 of thearm 6 carr 1ed by the releasing lever 7. The re leasing lever 7 ispivotally secured to the back plate 1 as at 8 and is provided with anotch upon its upper edge which is adapted to be engaged by the angleend of the rais- 1ng arm 9 carrled by the control shaft 10.

A stop arm 11 is carried by the shaft 10 and is provided with adownwardly extendlng end adapted to engage one of the laterallyextending lugs 12 carried by the checklng gear 13. A stop arm 1 1 isalso carried by the control shaft 10 and is provided with a laterallyextending end being adapted to en age notches 15 formed in the checkdisk 16. The arm 17 which controls the number of strikes by each clapperis also carried bv the controller shaft 10. This arm 17 is bentintermediate its end as at 18 so as to accommodate itself to the gearingcarried by the frame. The end of the arm 17 is flattened and bentdownwardly for forming a tooth gripping blade as at 19 for engaging theteeth of the counting wheel 20 hereinafter described. A shaft 21 iscarried near the upper end of the frame upon which is mounted the checkgear 13. A small gear 22 is secured to the gear 13 and meshes with agear 23 carried by the shaft 29. A sleeve 25 is carried by the shaft 21and one end of the shifting bracket 26 is secured thereto. The sleeve 25is cut away at 27 to allow the gear 28 to rotate.

The strike operating shaft 29 is carried by the frame between thecontroller shaft 10 and the shaft 21. This shaft 29 carries the gear 23hereinbefore mentioned, to which gear is secured the stop disk 16. Thestrike operating cam 30 is carried by a sleeve 31 which works upon theshaft 29. A pin 32 is carried by the shaft 29 and works in the slot 33formed in the sleeve 31 so as to allow longitudinal movement of thesleeve but prevents the rotary movement thereof relative to the shaft29. The striking cam 30 comprises a pair of fingers 34 which are curvedupon their back to allow the clapper arms 35 to be easily operated. Oneend of the shifting bracket 26 is carried by the shaft 29 and a collar36 is placed upon the collar 31 to hold the same in engagement with oneend of the shifting bracket 26. A lug 37 is carried by one side of theshifting bracket 26 and is provided with a projecting finger 38 whichfinger is adapted to be engaged by the shifting arm 39 of the shiftingmechanism. A gear 40 is carried by the shaft 29 and meshes with the gear28 car ried by the shaft 28 for imparting rotary movement to thecounting gear 20 through the medium of the gear 42. A gear 43 is keyedto the gear 28 for engaging the regular clock gearing.

A cam wheel 44 is carried by the main shaft 3 and comprises a pair ofspaced disks between which fits the depending end of the shifting arm45. The arms 39 and 45 are carried by a shaft 46 which is supported upona bracket 47, which bracket is sup ported by the front plate 2. A numberof gears 48, 49, and 50 are carried by the shaft 3 for connecting withthe diiferent gears for operating the hour, minute and date hand of theclock in the usual manner.

A spacing member 51 is positioned between the back plate 1 and the frontplate 2 and carries a hanger bracket 52 intermediate its ends. A clappersupporting shaft 53 is supported upon each side of the hanger bracket 52and each of the shafts 53 has a coil spring wound around the same fornor mally holding the striking end 54 in engagement with the bell orsignal. A finger 55 is carried by each shaft and is provided with anangle end fitting in the stop notch 56 formed in the plates 1 and 2 Theupper ends of the clapper arms 35 are bent so as to face each other andare adapted to be engaged by the cammember 30 as hereinafter described.

From the foregoing description it will be obvious that as the main shaft3 is rotated every one fourth of a turn the releasing lever 7 will beraised thereby raising the arm 9 and rotating the shaft 10, whereby allthe arms carried by the shaft 10 will be raised and allowing thecounting wheel to rotate and cause the clapper which is adapted toindicate the quarter of an hour to operate. This clapper just mentionedwill be operated by the cam 30 as the same rotates, the rotary movementbeing imparted thereto by the gears 20, 42, 28 and 40. The arms whichare carried by the shaft 10 are held in their normal position by meansof the spring 57 which bears upon the arm 11. As the shaft is operatedone whole revolution the curved portion 58 engages the depending end ofthe arm 45 thereby swinging the same and causing the shifting bracket 26to slide upon the shaft 29 so as to have the cam 30 engage the clapperwhich engages the hour signal and operate the same. As the shaft 3continues to rotate the cam 30 will be again brought back to its normalposition. The number of strikes is regulated by the counting wheel 20which is engaged by the flattened end. 19 of the arm 17. This wheel 20is provided with teeth formed upon the edge thereof in the followingmanner: one deep tooth indicating the end of an hour, one deep toothindicating the first quarter of the hour, one shallow tooth and one deeptooth indicating a second quarter of the hour, two shallow teeth and onedeep tooth indicating the third quarter of the hour and finally thenumber of teeth to indicate the succeeding hour. This is repeated aroundthe entire wheel, the arrangement between each hour being the same asthat just stated.
